Calculator for weight and balance for small airplanes

Config

Add the configuration for each plane in src/input/config.json in the following format:

{
    "name": "Name of airplane"
    "levers": {
        "base": lever for base wright,
        "fuel": lever for fuel weigh
    },
    "max_weights": {
        "max_take_off_weight" : some weight
        "max_fuel": max fuel in kg
    },
    "vertices" : [[ // 6 coordinate pairs
        x,
        y
    ]]
}

Levers are restricted to:

• base (Mandatory)
• fuel (Mandatory)
• bagage
• bagage_back
• bagage_front
• bagage_wings
• pilot (Mandatory)
• co_pilot (Mandatory)
• passenger_left
• passenger_right

Input

Currently the weight and balance is calculated by parsing a json file: src/input.json Add your input weights in the following format:

{
    "name": "Name of airplane",
    "values" {
        "base": "453.5",
        "fuel": "85.0",
        "bagage_back": "0.0",
        "bagage_front": "1.0",
        "bagage_wings": "2.0",
        "pilot": "70.0",
        "co_pilot": "0.0"
    }
}

Input points are restricted to:

• name (Mandatory)
• base (Mandatory)
• fuel (Mandatory)
• bagage
• bagage_back
• bagage_front
• bagage_wings
• pilot (Mandatory)
• co_pilot (Mandatory)
• passenger_left
• passenger_right

Weight should be in kilograms.

Running

cargo run -- --path /path/to/input.json

Output

Plane: "Your plane" has W&B that is ok: true Plane: "Your plane" has W&B point at: ViktArm { weight: 611.5, lever: 175.40662 }

Limitations

Calculations can be done on two- or four-seater planes.
